If you would like to see the math calculations used to determine your calorie range; check out this link: www.sparkpeople.com/resource/calorie_calcu
I think your SP calorie range is correct and will result in about 1-2 pounds lost weekly. Experiment and see how you progress.
If you udate your weight, our SP program will adjust your calorie range when appropriate.
Also keep your exercise plan (calories burned through planned exercise) current too.
